I. Metamorphism Diagram
1) Contact metamorphism ~ When rock undergoes metamorphism due to contact with magma or lava.
2) Regional metamorphism ~ When rock undergoes metamorphism do to tremendous pressure (deeply buried, plate collision zones).

II. Metamorphic Processes
1) Foliated: Rocks that have mineral grains that are aligned by pressure
2) Non-foliated: Rocks that lack mineral grain alignment
